Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the ....Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the minimum population sizes and habitat areas required for long-term survival. My prior research has validated the predictive accuracy of PVA. This research will deliver practical guidelines for managing threatened species.Read moreRead less

This project will greatly extend our understanding of the impact of demographic change and ageing on the workforce. It will develop a conceptual framework to strategically inform workforce development and a workforce planning model to assist Australian workplaces to respond to the challenge of demographic change and ageing. The need to develop a better understanding of, and respond to, the implications of demographic change and ageing for workforce development in Australia has been recognised nationally through the National Strategy for Ageing and is of direct relevance to the ARC's national research priority Ageing Well, Ageing Productively.

The demographic consequences of migration to, from and within Australia. The long-term demographic consequences of migration to, from and within Australia, and the dynamic pathways that produced them, will be studied. This will involve the identification of the specific contributions made by international and internal migration to the age and sex population compositions of nine birthplace-specific populations from 1981 to 2011. To do this, publically available data will be collected and augmente ....The demographic consequences of migration to, from and within Australia. The long-term demographic consequences of migration to, from and within Australia, and the dynamic pathways that produced them, will be studied. This will involve the identification of the specific contributions made by international and internal migration to the age and sex population compositions of nine birthplace-specific populations from 1981 to 2011. To do this, publically available data will be collected and augmented with statistical methods to provide a complete, consistent account of population change for around 60 subnational areas. As migration and population change underpins many aspects of societal change in Australia, this research aims to provide an invaluable resource to other scientists and policy makers.Read moreRead less
Where migrants go: A study of immigrants' post-arrival moves in Australia . The project aims to establish the geographical and occupational trajectories of different migrant groups after arrival in Australia. Migration within Australia is a key driver of economic, demographic and social change. Recognising the growing diversity of immigrants, including the rapid rise in temporary migration, the project examines post-arrival moves of immigrants by visa type, country of birth and year of arrival. ....Where migrants go: A study of immigrants' post-arrival moves in Australia . The project aims to establish the geographical and occupational trajectories of different migrant groups after arrival in Australia. Migration within Australia is a key driver of economic, demographic and social change. Recognising the growing diversity of immigrants, including the rapid rise in temporary migration, the project examines post-arrival moves of immigrants by visa type, country of birth and year of arrival. It seeks to improve understanding of the incidence, spatial patterns and drivers of migrants’ movement within Australia and the socio-demographic impact on regions and individuals. Such understanding is an essential first step to the formulation of effective immigration and settlement policies and programs.Read moreRead less
Improved Indigenous population projections for policy and planning. This project will use a range of methods to understand the population dynamics of the Australian Aboriginal and Torres Strait Islander (Indigenous) population. This information will allow policy makers to plan and target resources and help Indigenous organisations understand what is happening to the population in their communities.
Causes and consequences of population turnover in the Northern Territory. The Northern Territory experiences an extraordinarily high rate of population turnover. Approximately one quarter (compared to less than 10% for most other states) of the Territory's resident population in 2001 had lived somewhere else 5 years earlier. The research will examine the characteristics and causes of this turnover as well as its long-term implications for the composition and associated planning capacity of the N ....Causes and consequences of population turnover in the Northern Territory. The Northern Territory experiences an extraordinarily high rate of population turnover. Approximately one quarter (compared to less than 10% for most other states) of the Territory's resident population in 2001 had lived somewhere else 5 years earlier. The research will examine the characteristics and causes of this turnover as well as its long-term implications for the composition and associated planning capacity of the NT population. Of particular interest is the effect of population transience on the establishment, maintenance, and continuation of knowledge systems, both desert and tropical.Read moreRead less
Plant-herbivore interactions: a model two-species system from northern Australia. The proposed research addresses a critical aspect of magpie goose ecology. Understanding the interaction between the birds and the bulbs is critical to respond effectively to past and threatened losses of important sedge habitats to sea level rise. This knowledge will inform management of the Kakadu World Heritage Site and an iconic waterfowl of great cultural and economic significance. In addition to their importa ....Plant-herbivore interactions: a model two-species system from northern Australia. The proposed research addresses a critical aspect of magpie goose ecology. Understanding the interaction between the birds and the bulbs is critical to respond effectively to past and threatened losses of important sedge habitats to sea level rise. This knowledge will inform management of the Kakadu World Heritage Site and an iconic waterfowl of great cultural and economic significance. In addition to their importance as a Gondwanan relic and sole member of the Family Anseranatidae, the species is an important food-source for Aboriginal people, and tourists travel to the Kakadu wetlands to witness huge dry season congregations.Read moreRead less

This project aims to create more robust, detailed, and accurate small area population forecasts, and implement them in a sophisticated forecasting system for one jurisdiction in Australia, USA, UK and Canada. The project is significant as it expects to generate a suite of new and innovative methods, theory, and population forecasts that will be useful to researchers and planners both in Australia and overseas. Expected outcomes include new forecasting methods, associated computer code, many open-access academic papers, and new international collaborations. More detailed and reliable population forecasts will bring substantial benefits to those planning our future infrastructure requirements (e.g. schools, hospitals, housing and transport).

Landscape-scale population dynamics of open forests in the Australian monsoon tropics. Over the last century there has been a trend of increasing tree cover in many landscapes. Yet the causes of this globally important ecological phenomenon are poorly understood, but may include the effects of climate, fire, grazing and CO2. We will determine how an area of forest has changed over 50 years in Kakadu National Park, linking forest demography with remote sensing techniques, re-measurement and analy ....Landscape-scale population dynamics of open forests in the Australian monsoon tropics. Over the last century there has been a trend of increasing tree cover in many landscapes. Yet the causes of this globally important ecological phenomenon are poorly understood, but may include the effects of climate, fire, grazing and CO2. We will determine how an area of forest has changed over 50 years in Kakadu National Park, linking forest demography with remote sensing techniques, re-measurement and analysis of long-term tree demography datasets, and simulation models of tree population dynamics on a landscape scale. This will provide a scientific framework to develop sustainable land management and the conservation of Australia's forest biodiversity.Read moreRead less
Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project t ....Ecological-epidemiological models of feral swamp buffalo control in northern Australia. This research is locally, nationally and internationally significant because it 1) improves the capacity of the Northern Territory and its traditional aboriginal owners to manage together this prevalent species in an effort to minimise disturbance to native flora and fauna and to understand the long-term implications of continued proliferation, 2) provides a nationally relevant system to monitor and project the spread of disease through feral animal populations in Australia, and 3) combines quantitative data and robust analytical tools that can be used as a template for solving many broad-scale feral animal problems around the world.Read moreRead less
